1,2-Disubstituted [(η6-Arene)Cr(CO)>3>] Complexes by Sequential Nucleophilic Addition/endo-Hydride Abstraction

Ripa, Alberto
Published in Chemistry - A European Journal. 1998, vol. 4, no. 2, p. 251-259
Abstract The surprising answer to the question Are the structural characteristics of the product of the nucleophilic addition to complex 1 those of a cyclohexadienyl complex (2 a) or those of a diene aza-enolate complex (2 b)? is: both. This is indicated by the X-ray structure determination of the complex with R=naphthyl. An unprecedented endo-hydride abstraction concludes the sequence that provides a new route to 1,2-substituted planar chiral [(n6-arene)Cr(CO)3] compounds.
